Performed on Feb. 29, 2012 at the U.S. Army Yuma Proving Grounds, this is the third in a series of the most flight-like parachute tests to date with a representative parachute compartment for the Orion spacecraft. It is the first such test to use a capsule shape representing Orion, known as a Parachute Test Vehicle. This video is narrated by Chris Johnson, project manager of the Orion Capsule Parachute Assembly Project. Topics: NASA, Orion, Orion B-roll, Orion Construction, Drop Test

Video b-roll of the design, development and testing of NASA's Orion spacecraft. Orion will serve as the exploration vehicle that will carry NASAâs astronauts to destinations such as asteroids, our moon, the moons of Mars, and one day Mars itself.

The suspension characteristics of agricultural tractors are dictated mainly by the characteristics of the tyres as they do not have spring suspension system like those provided on road vehicles. The tyre can be modeled approximately as a spring-damper system exhibiting under damped vibration. The apparent spring stiffness and damping coefficient of a tractor front tyre was estimated in a non-rolling condition in the laboratory. For this purpose a test rig was fabricated. It had provision to... Topics: Under Damped Vibration, Spring Constant, Damping Coefficient, Pneumatic Tyre and Drop test
The objective of this research is to investigate the solder joint reliability of board-level 3D pyramid package-on-package (POP) stacked-die packages in transient drop analysis. Three kinds of lead-free solder alloy, Sn4Ag0.5Cu, Sn3.5Ag0.5Cu and Sn3.5Ag are introduced to demonstrate the transient dynamic response subjected to JEDEC sine wave pulse-controlled drop test. In order to evaluate the structure of the interested area a strip model sliced from, the full test vehicle is introduced in...
